TRNSYS – THE UNIVERSAL TOOL FOR CLIMATE ENGINEERING

TRNSYS is a complete and extensible simulation environment for the transient simulation of thermal systems including multi-zone buildings.

It is used by engineers and researchers around the world to validate new energy concepts, from simple solar domestic hot water systems to the design and simulation of buildings and their equipment, including control strategies, occupant behaviour, alternative energy systems (wind, solar, photovoltaic, hydrogen systems), etc. Throughout its thirty year history TRNSYS has been under continual enhancement by an international group.

Modular and open structure e.g. interative calls with other programs during the simulation, integration of user written components
